I'm receiving the following events in my event logs on a member server:
When I check the Event System log:
Event ID: 4
The kerberos client received a KRB_AP_ERR_MODIFIED error from the server host/nycmaildpm.mydomain.com. The target name used was localhost. This indicates that the password used to encrypt the kerberos service ticket is different than that on the target server. Commonly, this is due to identically named machine accounts in the target realm (mydomain.com), and client realm.
I've verified there isn't another computer account in the domain with the same name -- nycmaildpm. If anyone has come across this before, please let me know.
